The Loud'n Proud by Mad Professor is a vintage 4-input Marshall in a box with a boost/fuzz. It is a compact pedal with a complete amp signal path replicated inside, including the preamp and power amp containing phase inverter, push- pull stage, and output transformer simulation. The pedal is designed to sound and behave like a real amp, offering a moderate amount of gain and a boost/fuzz feature to enhance the overdrive circuit.
The pedal features controls for gain, output volume, bass, middle, treble, presence, fuzz volume, boost/fuzz, and character switch for two different voicings. The character switch offers options for tighter bass and slightly compressed tone or looser bass with maximum dynamics. The pedal is suitable for emulating vintage Plexi and JTM45 Marshall amplifiers, and it is ideal for achieving classic rock tones associated with bands and artists such as AC/DC, Cream, Jimi Hendrix, Led Zeppelin, Free, and more.
